Dead Coin Battery
The most frequent reason for a key fob that does not be able to lock or unlock doors is a dead coin battery. It is also among the most simple problems to fix since it is usually replaced in a matter of minutes. To avoid getting a faulty coin battery, make sure you make sure you use a new battery that has the same voltage, size and specifications as the original one. Do not expose a battery to pure water, such as rain, clean tap water, or even soda, as this could damage the internal chip. If the key fob doesn't function after reprogramming it using an original key, you can go to an authorized dealer.

This is a common problem with older batteries, particularly if they haven't been charged for a long period of time. To determine if your battery's terminals are corrosion free, you can utilize a multimeter to test the conductivity. Set the meter to ohms, and touch one of its probes to the negative terminal of your Dawn. Touch the other probe on a metal surface of the chassis or engine. The reading should be close to zero ohms.
Another sign of a weak battery in your Dawn is the sound that you hear when you attempt to start the engine. This is due to the fact that the starter solenoid and other accessories require high currents of electricity, while the engine needs a low current to work - this means that the battery is unable to provide enough charge.
Water Damage

If the key fails to function, it is possible that the 12 volt batteries or receiver modules are the cause. They must be replaced.
Issues with the Receiver Module
If you have tried a different cell but the remote keyfob is still not function, then it may be time to replace the receiver module. The receiver module receives radio frequency signals from your key fob and converts them into commands for the vehicle's electronic system. If the chip inside the module is damaged, it won't be able to communicate with other modules within the vehicle. To identify the issue, you'll need an OBD scanner that will show you what the on-board computer is telling it to do.
The metal clips that secure the battery in the key fob of your Dawn complete the circuit and keep it in position. These clips are susceptible to corroding and make the battery contacts useless. If you are replacing the battery, make sure it's the exact size and voltage to the previous one. Otherwise it could cause damage to the chip inside the key fob.

The interference could be caused by objects within the vicinity of your car, weather conditions and transmitters that operate on the same frequency band. Interference can be caused by a faulty receiver module. If you are not able to eliminate the interference, you may be able to use an extender or signal booster.
It is crucial to replace the button cell battery on your Dawn key fob in the event that it's drained.
